Question

Show transcribed image text A mass with v0 = 15 m/s collides with two identical balls which, are lined up vertically as in the diagram below. The incoming mass is timed directly at the contact point between the two balls, The collision is elastic, and there are no external forces acting. Kind the velocities of all three balls after the collision. Hint: The directions of the stationary balls after the collision can be found be considering the direction of the impulse they receive at the moment of impact.
